	<span lang=\"EN-GB\"><span style=\"font-family:Verdana;\">A polycrystalline dense Ti</span><sub><span style=\"font-family:Verdana;\">3</span></sub><span style=\"font-family:Verdana;\">SiC</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> based ceramic
material has been produced by several techniques. The effect of addition of TiC
and SiC is also studied. The </span></span><span style=\"font-family:Verdana;\" lang=\"EN-US\">T</span><span lang=\"EN-GB\"><span style=\"font-family:Verdana;\">i</span><sub><span style=\"font-family:Verdana;\">3</span></sub><span style=\"font-family:Verdana;\">SiC</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> material shows extraordinary electrical,
thermal and mechanical properties.</span></span><span style=\"font-family:Verdana;\" lang=\"EN-US\"> Furthermore, it shows a damage tolerance capability and oxidation
resistance.</span><span lang=\"EN-GB\"><span style=\"font-family:Verdana;\"> In this work, we have synthesized Ti</span><sub><span style=\"font-family:Verdana;\">3</span></sub><span style=\"font-family:Verdana;\">SiC</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> by
electro-thermal explosion chemical reaction (ETE) with high current density
(900 Amperes/a.u) followed by uniaxial pressure. The structural properties of
the as-prepared materials are studied by x-ray diffraction (XRD), scanning
electron microscope (SEM) and energy dispersive x-ray spectroscopy (EDX)
techniques. The chemical cartography, imaging and electronic properties are
investigated using Ultra-STEM and electron high energy loss resolution
spectroscopy (EELS) techniques, respectively. The surface of Ti</span><sub><span style=\"font-family:Verdana;\">3</span></sub><span style=\"font-family:Verdana;\">SiC</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> is characterized by means of X-ray photoelectron spectroscopy (XPS). High
resolution C 1s, Si 2p, Ti 2p, Ti 3s core level spectra are explained in terms
of crystallographic and electronic structure. Valence band spectrum is
performed to confirm the validity of the theoretical calculations.</span></span>
